Hi there. I'm writing a trap listener and using netsnmp, obviously.
I want to be able to join a multicast group before I bind the socket in
order to receive multicast traps.
When I call 'netsnmp_transport_open_server("snmptrapd", "udp:162")' is there
any option I set prior to this or can I modif
pdu->transport_data_length);
which gives you a textual representation ...

Thanks but that hasn't worked, damn.
When a trap is recieved, I cast the corresponding pdu->transport_data to a
sockaddr_in like you said and the address I get is "2.0.11.184" and it never
changes. I find it remarkable that this is proving to be so difficult.

Apologies for this, but I truly mucked up the last thread when replying.
I'm trying to get the client ip address from a trap listener I wrote.
>From some digging about, it looks like I should be able to grab the ip from
"pdu->agent_addr" but I'm getting null when trying to print it out and

r = NULL;
sess.isAuthoritative = SNMP_SESS_UNKNOWNAUTH;
rc = snmp_add(session, t, NULL, NULL);
if (rc == NULL) {
snmp_sess_perror("exteritytrapd", session);
}
return rc;
}
Can anyone see anything that I'm doing wrong?
Thanks,

Hi there.
Does net-snmp provide a way to grab the IP address from whoever sent a
trap? Basically, in snmptrapd.c, you have the main
'while(netsnmp_running)' loop and inside that 'snmp_read()' is called which
hands a pdu to a callback function. I want to get the ip address of the
system that sent
id of but at least it's working.
Thanks.

Hi,
Trying to strip snmptrapd.c down to the essentials. I just want to be able
to receive traps and print them to the terminal for now.
Here is what I have so far: http://pastebin.com/7W6Gc7ne
I am trying to compile this to test. I don't expect it to work yet. Here
is my Makefile:

Nevermind, I am being an idiot. I don't need to use libpcap since traps are
being broadcast.

handed to me from libpcap. Is there an alternative that I have missed?
Note, I am not writing a daemon to accept traps, I am 'sniffing' traps from
a local LAN.
Thanks for any help.

Hi.
I am currently writing a trap listener. Basically traps are being sent to
255.255.255.255 on port 162 and I am 'sniffing' the traps using libpcap
which was simple enough. But now I have raw snmp trap packets and I do not
fancy learning how to parse these myself. Are there a set of simple

Hi,
I've been tasked with writing a trap listener in C which will then take
specific device info from these traps and shove them in a database
(postgresql).
Can somebody point me in the right direction? I have had a look at
apps/snmptrap*.c but I quickly ran out of steam when trying to follow it
